Wiring example of voltage detection cable
This section shows the wiring examples of the voltage detection cables at the base metal side to the base
metal.
4.6.3.1
Wiring examples for plural welding stages
Connect the voltage detection cable at the base metal side to the stage to which the cable on the base metal
side was last connected.
4.6.3.2
Wiring example when power is supplied with a power feeding brush to the
positioner
Insulate the power feeding brush from the jig base and connect the voltage detection cable (base metal
side) to the jig base.
T I P S
• Before wiring the voltage detection cable, check that conduction between the jig base and
the base metal is stable.
